# Traefik integration for Grafana Cloud

Traefik is a dynamic load balancer designed for ease of configuration, especially in dynamic environments. It supports automatic discovery of services, metrics, tracing, and has Let’s Encrypt support out of the box. Traefik provides a “ready to go” system for serving production traffic with these additions.

This integration includes 3 useful alerts and 1 pre-built dashboard to help monitor and visualize Traefik metrics.

## Before you begin

You need to enable the Prometheus metrics endpoint in your Traefik node. Please follow the [official documentation](https://doc.traefik.io/traefik/observability/metrics/prometheus/).

## Install Traefik integration for Grafana Cloud

1. In your Grafana Cloud stack, click **Connections** in the left-hand menu.
2. Find **Traefik** and click its tile to open the integration.
3. Review the prerequisites in the **Configuration Details** tab and set up Grafana Alloy to send Traefik metrics to your Grafana Cloud instance.
4. Click **Install** to add this integration’s pre-built dashboard and alerts to your Grafana Cloud instance, and you can start monitoring your Traefik setup.

## Configuration snippets for Grafana Alloy

### Simple mode

These snippets are configured to scrape a single Traefik instance running locally with default ports.

First, **manually** copy and append the following snippets into your alloy configuration file.

### Metrics snippets

Alloy ![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy

```alloy
discovery.relabel "metrics_integrations_integrations_traefik" {
	targets = [{
		__address__ = "localhost:8080",
	}]

	rule {
		target_label = "instance"
		replacement  = constants.hostname
	}
}

prometheus.scrape "metrics_integrations_integrations_traefik" {
	targets    = discovery.relabel.metrics_integrations_integrations_traefik.output
	forward_to = [prometheus.remote_write.metrics_service.receiver]
	job_name   = "integrations/traefik"
}
```

### Advanced mode

The following snippets provide examples to guide you through the configuration process.

To instruct Grafana Alloy to scrape your Traefik instances, **manually** copy and append the snippets to your alloy configuration file, then follow subsequent instructions.

### Advanced metrics snippets

Alloy ![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy

```alloy
discovery.relabel "metrics_integrations_integrations_traefik" {
	targets = [{
		__address__ = "localhost:8080",
	}]

	rule {
		target_label = "instance"
		replacement  = constants.hostname
	}
}

prometheus.scrape "metrics_integrations_integrations_traefik" {
	targets    = discovery.relabel.metrics_integrations_integrations_traefik.output
	forward_to = [prometheus.remote_write.metrics_service.receiver]
	job_name   = "integrations/traefik"
}
```

To monitor your Traefik instance, you must use a [discovery.relabel](/docs/alloy/latest/reference/components/discovery.relabel/) component to discover your Traefik Prometheus endpoint and apply appropriate labels, followed by a [prometheus.scrape](/docs/alloy/latest/reference/components/prometheus.scrape) component to scrape it.

Configure the following properties within each `discovery.relabel` component:

- `__address__`: The address to your Traefik Prometheus metrics endpoint.
- `instance` label: `constants.hostname` sets the `instance` label to your Grafana Alloy server hostname. If that is not suitable, change it to a value uniquely identifies this Traefik instance.

If you have multiple Traefik servers to scrape, configure one `discovery.relabel` for each and scrape them by including each under `targets` within the `prometheus.scrape` component.

## Dashboards

The Traefik integration installs the following dashboards in your Grafana Cloud instance to help monitor your system.

| TraefikTLSCertificatesExpiringSoon    | Warning: A Traefik-served TLS certificate will expire soon.       |

## Metrics

The most important metrics provided by the Traefik integration, which are used on the pre-built dashboard and Prometheus alerts, are as follows:

- traefik\_config\_reloads\_failure\_total
- traefik\_entrypoint\_requests\_total
- traefik\_service\_request\_duration\_seconds\_sum
- traefik\_service\_requests\_total
- traefik\_tls\_certs\_not\_after

```md
# 1.0.0 - September 2025

* Assertify Traefik integration by
  * Adding Asserts specific labels to Traefik metrics in recording rules
  * Adding Asserts environment variables as selectors in Traefik dashboards
  * Adding SAAFE mapping for Traefik alerts
* Updated traefik-mixin with new dashboard that better matches Asserts templates for Data source, Job and Instance variables.
* Updated jsonnet-libs with some new helper functions for Asserts variables

# 0.0.6 - September 2023

* New Filter Metrics option for configuring the Grafana Agent, which saves on metrics cost by dropping any metric not used by this integration. Beware that anything custom built using metrics that are not on the snippet will stop working.
* New hostname relabel option, which applies the instance name you write on the text box to the Grafana Agent configuration snippets, making it easier and less error prone to configure this mandatory label.

# 0.0.5 - March 2023

* Fix errors rate calculation

# 0.0.4 - September 2022

* Update total calls panel
* Fix traefik panel's query with hardcoded value
* Add job variable refresh on time range (for faster dashboard update when very first metric comes to prometheus)
* Add negative offset for better calculation of total number of calls/error over dashboard's range

# 0.0.3 - September 2022

* Update dashboard panels descriptions.

# 0.0.2 - October 2021

* Update mixin to latest version:
  - Update queries to use $__rate_interval

# 0.0.1 - July 2021

* Initial release.
```

## Cost

By connecting your Traefik instance to Grafana Cloud, you might incur charges. To view information on the number of active series that your Grafana Cloud account uses for metrics included in each Cloud tier, see [Active series and dpm usage](/docs/grafana-cloud/fundamentals/active-series-and-dpm/) and [Cloud tier pricing](/products/cloud/pricing/).
